hey XDA peeps,
Seasoned Android modifier here.
Got a LG Optimus One from Telus (Canada) (P500h), came with 2.3.3 .
I can root it, flash custom Roms, Flash the Baseband Fix, Flash a custom Kernel and restore it back to Stock 2.3.3.
The only thing I can't make it do, is make my custom ROMs save my Rogers Wirelss APNs !!!
I can't seem to find a KDZ file for the V10 (2.2.1) firmware and two of us cannot figure out how to flash the DZ files, (Cannot Find Monitor Port?? Tried 2 different computers). From my understanding, its best to start from the 2.2 Software, but I can't find it for my P500h Telus Canada.
I see that I am not the only one who is having the APN Problem.
So what I'm asking is
A) How do I fix this APN not saving issue
B) Which CM ROM should I flash that does not have this issue
Thanks!
You have to downgrade your baseband to old one then you can save apn ...
Flash cm6.5.8 it is stable

So, i gather that the zip file ive been flashin via CWM called "baseband fix" is not downgrading my baseband.
Is this a file I have to flash via KDZ? Can anyone link me to the file? I've looked high and low for such a file.

You're welcome,
I would like you to press thnx
Thanks guys, last time i installed that rom it failed miserably. I tried again and it works great and it seems i didn't need to flash the new baseband coming from the stock 2.3.3 software.
Thanks a lot!

Here's a link to where you can read more about getting the new baseband:
http://forum.xda-developers.com/showthread.php?t=1140862
BUT! for trying out CM7 on your phone you currently do NOT need the new baseband, although you might need it in the future.
All you need to do is install ROM Manager from the market > flash custom recovery from it > download the required files and follow the instructions available here:
http://forum.xda-developers.com/showthread.php?t=946354
Hope that helps
What about gsm.what is gsm?
Sent from my LG-P500 using Tapatalk
GSM = Global System for Mobile Communications more or less your phone's ability to work as a phone/connect to your provider's network.
The tricky part with basebands and different ROMs is that once you flash the new baseband (update to official GingerBread), you will not have gsm/network if you go back to a ROM based on the old baseband. Up side is, Mik has taken care of it by coming out with a workaround, which you can find in the FAQ section in the CM7 link I posted earlier.
And btw, searching the forums is a good way to find a lot of useful info, don't get me wrong, I'm new here too, but all the answers I'm giving you, I've managed to find with the search options
Ok thanks dude this is very helpful

Hi all I am having problems flashing a different rom to my lg optimus p500h. I have tried flashing a couple different roms to my phone but when I boot up I don't have service. I looked for my IMEI number on my phone and it's blank. How do I flash a rom and keep my IMEI number?
possibly you dont read carefully what roms you can use when flashing this phone.
there are 2 sorts of baseband (needed for gsm and data service) - if you are coming
from LG stock rom you have to decide what rom you want to use and than you have
eventually flash the baseband too... its all written here in general topic, so take a look
at previous posts/topics about baseband and what rom to use.
What would be considered the stock rom? It used to have 2.1 on it but I updated it a couple times and it now has 2.33.

Now you are on new baseband... so u cant use 99% of the roms available on xda...
U will need to downgrade back to 2.2.1, just the way u upgraded to use those 99% roms...

Ok how do I downgrade? I have done some searching but can't find anything.
Is there any I can use without downgrading?

i have this p500 allmost a year so i would love to know if there is a way to flash the new baseband because i want to flash the NightlyFourE V4.6 rom so if there is any "HOWTO" or something like that please post this in here
There are many good tutorials around. The easiest way is to update to official GB from LG. In this way, you'll get the new BB automatically. After that, you can root the device, install clockworkmod from market and get any ROM for the new BB.

and if i have the NightlyFourE 4.4.1 i can just update with the official GB from LG without problems because its not a stock rom...

All you had to do is search lol.
But anyway follow the link in my signature, the method in my tutorial is installing the new gingerbread update using kdz, and helps you re-root and install correct recovery
So i want to try cm9 on my p509. I've tried many times to upgrade the baseband, but whenever i do i get no gsm and my imei disappears. trust me i've followed the guide EXACTLY. so i just stick with old bb. I want to flash to this cm9 http://forum.xda-developers.com/showthread.php?t=1614420. My question is if i flash this rom will it brick my phone (because i'm on old bb). if it won't then can someone post a link to a old bb fix so i can get data working on my phone when i flash it. I need this info urgently because i'm about to travel in a few hours and want to flash before i do. Thank you!
It will not brick your phone, and I haven't the FIX yet.
I'm searching for it now

that what i've been doing, but it never works properly
i've followed all the directions, and it doesn't work. i downloaded the v20 file and extracted with winzip to update to v20.
Do you've restored the NV2-file after flashing the new baseband?
Just a note, try not to mess around with nv2 it can create such a hasle in the end

no was i supposed to?
Guys i'm stupid. i was trying to update the baseband while using cm 7.2 (i used an old bb-fix for data) so i flashed cm9,, and then updated the baseband and it works!!!! so now my question is, if i re-flash cm 7.2 and am still on the upgraded baseband will it work? (yes i know i can just restore a nandroid backup, but i just need to know this information)

I think, it doesn't work. The ROM boots, but you have no signal etc. Even restore a nandroidbackup doesn't downgrade the baseband.

Why would he need to downgrade
Both cm7.2 and cm9 run on new baseband,right?
Though not sure what restoring nandroid will do in this case as then it would have old-bb fix on new baseband:cyclops:
yeah i hear ya. so is it reccomended that i reflash cm 7.2 so then i coulld stay on new baseband? then it would be easier for me to flash roms for new bb right?
okay... i am gonna explain this and hope i am right..sry for big post
Our phone has many partitions like(system,data,boot,recovery,cache,etc)
The mbn files that you see in P500-v20G-baseband.7z are partition images(or pieces of it or bin file or something similar....am not sure)
Now to install a custom rom, you format system,data,cache(or boot too in some cases) and then flash the rom, which basically copies new files to these partitions.
SO,custom rom does not affect other partitions present on your phone.
However when you install stock through kdz, it basically wipes your whole phone and install each partition again(including the one containing baseband).So, after installing a kdz...you are stuck with that baseband no matter which rom you install through recovery unless you install a kdz again with diff baseband.
The lgmdp method only changes the partition containing baseband (amss.mbn). So,again custom roms have no effect on baseband.
Now, to answer your ques.

No, you dont need to reflash any other rom. You ARE on new baseband now and can flash any rom for new bb and it will work.
Note:All info above may or may not be entirely correct.Its just how i think it works.:good:

Mod plz add this to sticky or link it in sticky
As we know there are two types of baseband's available for our device, old baseband which is used by froyo and some gingerbread rom's and new baseband that is used by gingerbread onwards.
To switch baseband you either need to flash baseband through lgmdp or flash firmware using kdz and both involves a substantial degree of risk of bricking your device.
What I will be telling will not actually change your baseband but will make the ROM compatible with the baseband you are using. So here it is how it goes.
-> If you are having old baseband and want to use new baseband ROM, flash this after flashing ROM

Note:- Patch for old baseband was originally made by adfadd and thats where idea came for creating a patch for new baseband. While the patch by adfadd is long lost in pile of threads, this is where this thread will come handy.
Flashing baseband through LGMDP cannot brick your device,only flashing full firmwares via LGMDp or KDZ_FW_UPD can have chance to brick

what abt if u get nv2 corrupted
Manual search fix
Here is the libril.so for manual search fix. My friend tested it on new baseband and it works.
So, probably for all new basebands including funnysim may work for gingerbread, ics and jellybean. Please test it on and report.
Good job.

i looked into the zip file and found that a few lib files are added by flashing the patch. would this affect the performance? my phone works fine in 90% of the time. however, sometimes it is just too laggy to even answer calls. it could become normal after some time, say 30s ro 1min.
i dont have this problem when i was using roms based on the old baseband. so i am wondering what would the patch do to the system.
thanks.

those libs aren't going to affect performance in any way... its the ROM & kernel that affects performance.
Am I mistaken, or is there a flashable zip to undo the old bb fix?
